UNITED STATES or BOSTON,

SEAM FOR SEWED ARTICLES.

like letters on the drawing representing like parts. This invention consists in a novel: seam or hem for sewed articles-in which a-main layer of textile or similar material is united to a superimposed layer of material by stitches, the threads of whichare concatenated or locked, .one row. of stitches passing into and from the upper sideof the main layer of material, the other row of stitches entering the folded edge of the superim osed layer and passing from the upper side of said layer back of its folded edge. 1

For the production'ofthe seam herein described, I employ two threads one ofwhich may be, for example, a strong cotton or linen thread, and the other a silk thread, the cotton or linen or first thread being laid close to the elge of the superimposed' m'aterial, so as to be drawn by the tension practically out of sight in the finished seam and only the silk or second thread crossing the edge of the'superimposed layer andappearlin ng,

needle in th mg in sight. Thus in the manufacture" of first-class clothing, that part'of the seam which is ex osed will show a silk. thread, and the loc ting thread, usually of g? cotton, will be substantiallyor wholly concealed in the material. Sometimes it is desiredto at-' tach a white. sik lining into acoat composed of black or very dark material, and to do this work properly the thread going into the body material should be substantially of the color of the body material, and the interlock ing thread which is to cross the edgeof the which may be considered the superimposed layer of material, should be of the same color as the superimposed material.

he present seam enables thls to be done in a'sat sfactorymanners Figure 1 shows a main layer of textile or similar material with a superimposed layer thereon showing the seam of my invention inthe inai n material ;'Fig. 2 is a like view with the needle in the superimposed material; Fig. 3 is a like view with the needle Specification of Letters Patent.

H

In forming the seam the point of the needle instead of entering thesuperimposed layer at itsup er side at a distance back of its folded edge, and emerging'from said superim osed ma: terial at its folded edge as in. my l atent No. 690385, granted January 7, 1902, approaches rial, enters the folded e go, and emerges from;'the upper side of the superimposed material back of its folded edge.

Bearing in mind that the needle, the threads and the gerated in the drawings that the interlooping of the threads may be better seen to thus enable the stitch to be described,.-I will now particularly refer to the drawin s.

The needle 6 carrying the nee le thread 0 enters the main material an at one thrust, see Fig. 1, parallel, with the folded edge of the superimposed material 112., and
